1 Claim. (Cl. 189-66) The object of this invention is to provide abasement window combining frame and sash which will permit doublesealing against the weather without overlapping of the sections oneither the interior or exterior. The entire frame and sash may be madeof extruded structural members. This inventive construction enables thewindow sash to be opened to a horizontal position of rest that is at a90 angle relative to the frame, and held in this position by the weightof the sash acting on the window frame. The sash may easily be removedand replaced without disturbing the frame assembly or removing any partthereof. When the window is open, by moving outwardly the window sash toa desired position, two holding arms, which are arranged to slide in theframe, receive the weight of the sash through use of the fulerumprinciple. wardly on the top of the sash, that part of the sash touchingthe frame slides up until it is in Contact with a bearing face on eacharm. The weight of the sash operating on a fulcruin principle, forcesthe rear edge of the sash against the frame, firmly holding it there. Inthis position, and by slightly tilting the sash upwardly, it is possibleto raise the sash to any position on the frame, and upon releasing ithave it held in place against the frame.

The invention will be described with reference to the accompanyingdrawings, in which Fig. l is a View in elevation showing the frame andsash in position;

Referring to the drawing, a substantially rectangular frame, having apair of spaced-apart vertical extruded frame members 1 and a pair ofspaced-apart horizontal extruded members 2 and 2x is constructed of asize to fit a cellar or basement window opening.

As shown in Figs. lO and 4a, the extruded member 1 is provided with avertical exterior wall 3 adapted to engage the vertical exterior wall 4of the basement opening. The vertical frame exterior wall 3 ispreferably provided with a flange 5, which ange contacts the basementwall surface. The vertical frame member 2 is also provided with aninterior wall 6. A vertical wall 7 is disposed intermediate integrallyand perpendicularly to walls 3 and 6.

The interior wall 6, which is disposed inwardly toward the cellar, has asection 8 disposed in engagementwith the wall 4 of the basement cavity.The wall 6 is also provided with a vertical integral strip 9, which isspacedapart and parallel to frame wall 7. A set-back faceplate 10 isintegral with, perpendicular to and set back relative to exterior wall3. A strip 11 is integrally and perpendicnlarly united to the freeextremity of face plate l? and disposed in spaced-apart but opposedrelation to strip 9.

The vertical members 1 are solid integral units, since all the partsdescribed above` are longitudinal and thus may be extruded from a die.Thus the members 1, as well as all other longitudinal structural membersto be described hereinafter, may be made from metal, such as aluminum,by means of an extrusion die.

The vertical members 1 are identical but are assembled to the basementwalls 4 so that both of the walls 3 are disposed outwardly away from thebasement window cavity.

The detail structure of the horizontal frame members 2 is shown in Figs.6, 1l and 12. Turning to Fig. 6, it will be seen that the top horizontalframe 2 is somewhat different from the bottom frame 2x.

The top horizontal frame member 2 is provided with a horizontal ledge12, to which is perpendicularly and integrally attached a verticalexterior wall 13, preferably having a flange 14 adapted to contact theexterior surface of the basement wall 4. The interior edge of ledge 12is provided with a longitudinal depending leg 15 disposed at a rightangle to ledge 12. A` depending face-platel is integral with andperpendicular to ledge 12, and is disposed in set back relation toexterior wall 13.

The depending face-plate 16 is disposed in spaced apart relationship tothe depending leg 15, and is of a shorter length than is said leg 15. i

The bottom horizontal frame member 2x is provided with a horizontalledge 17 (Fig. 6), an interior upright wall 18, and an interiordepending wall 19 having a ange 20, adapted to contact the basement wall4. Wall 18 is integral with wall 19 and ledge 17, the two walls andledge forming a T-shape structure. The exterior end of ledge 17 ispreferably turned upward at an oblique angle to forni plate piece 21. Anupright face-plate 22, of a shorter length than upright wall 13, isintegral with ledge 17 and is spaced apart relative thereto.

As shown in Fig. 14 the horizontal frame members 2 extend beyond thevertical frame members 7 and are keyed into grooves or cut-outs disposedin said horizontal 3 frame members 2 to form a secured integrated frameunit.

Turning now to the sash (Figs. 7, 8 and 10), the sash unit is of arectangular shape made from four identical angular structural members23, disposed outwardly from the window panes 24. Each sash frame member23 has a center plate 25, to which is integrally united an exteriorplate 26 disposed outwardly at a right angle to plate 25. A second plate27 is disposed in spaced apart relationship to plate 26 and on the sameside of center plate 25. An angle plate 28 is integrally united to theinterior end of plate 25 on the side opposed to plate 28, said plate 28being provided with a flange 29 against which the window 24 rests.

As shown in Fig. 9, the sash is provided with a T-shaped separator piece30, the T arms of which have a raised flange 31 against which the windowpane 24 rests. A triangular layer of putty 32 is disposed against thewindow pane and the adjacent contacting structural members, therebykeeping the window pane 24 in place.

The sash is removably secured to the vertical frame members 2 (Figs. 4and l0) by means of opposite fulcrum arms 33 adapted to support theweight of the sash against the member 2. A button 34, provided with ashank 35 is secured to each fulcrum arm 33 by co-action with acylindrical separator 36 having a bore-hole. Each fulcrum arm and itsbutton is secured to the center plate 25` by means of a headed pin 37,which pin may be provided with screw threads adapted to engage thebore-hole walls of said separator 36.

The button 34 slides vertically in the grooved channel formed by opposedspaced apart walls 9 and 11, relative to plate 7 which latter is spacedapart from said walls 9 and 11. Pin 37 is secured to the vertical sashwall center plates 25 at a point intermediate its ends. As shown in Fig.6, the walls 9 and 11 are provided near their tops with curved cut-outs33 of a diameter greater than that of buttons 34, thus providing foreasy insertion or removal of said buttons 34 from confinement by stripsor tracks 9 and 11, thereby facilitating the entire removal of the sashand the two fulcrum arms away from the frame.

As shown in Figs. 8 and l0 the exterior walls 26 of the closed sash lieagainst face-pieces 16 and 22 of the top and bottom horizontal framemembers 2, and the vertical sash walls 26 lie against face-pieces 10 ofthe vertical members 1. Similarly in the closed sash, the short plates27 engage the wall 15 of the top horizontal frame member and wall 18 ofthe bottom horizontal frame member, while` plates 27 disposed in thevertical sash members 23 (Fig. 10) engage the interior of wall 6.

The overall result is that the rectangular sash when in closed positionengages the corresponding rectangular frame in a double spaced apartlinear manner on each of the four rectangular sides, thereby sealing outthe weather fromV the basement in a dual manner.

As shown in Figs. 4 and 4a the sash may be lifted upwardly by a handle39 (Fig. l5) secured to T-shaped separator 30. The top of the sash ismoved outwardly causing the part of the sash below pin 37 to moveinwardly. The sash then may be caused to assume a horizontal position(Figs, 3 and 4). The sash then may be moved up or down the members 1with the buttons 34 riding in the confining channels of the verticalmembers 1. In horizontal sash position the bottom sash wall 26 rests inweighted frictional contact with walls 10 of the vertical frame members,thereby preventing falling of the sash since the center of gravity ofthe horizontally extended sash tends to rotate it clockwise therebyforcing the edge of wall 26 to grippingly engage the frame walls 10.

The sash may be locked to the frame by means of an angular swing latch40 riveted by rivet 41 to the top of top sash frame plate 25 (Figs. 11and 12). 'I'he swing latchV 40 may be a single plate piece having acenter section 42, a depending finger grasp 43, and upright lug 44. Acooperating lock pin 45 is secured to center plate 12 of the tophorizontal frame member 2. In the closed position the lug 44 is disposedbehind pin 45 (Fig. 11) so that the sash cannot be raised. In the openposition, the finger grasp 43 is swung outwardly so that lug 44 isdisposed to one side of pin 45, thereby permitting the sash to beraised.

This invention has been described by means of an illustrative embodimentbut obviously it is of the broader scope as claimed herein.

Having described my invention, what I claim and desire to secure byLetters Patent is as follows:

A Casement window structure adapted for doubly sealing out the weatherand made from linear extruded structural members comprising a framehaving longitudinal substantially tubular and substantially rectangularextruded vertical members having channels therein, said channels beingof a T-shaped configuration with the stem of the channel forming a slotin said substantially tubular member and forming a pair of spaced apartoffset linear abutment and load bearing surfaces disposed on each sideof each slot, said frame having horizontal top and bottom frame members,the top frame member being substantially Z-shaped and the bottom framemember being sub stantially T-shaped, each of said top and bottom framemembers having a pair of offset spaced apart linear abutment non-loadingbearing surfaces, a sash adapted to both slide and swing and providedwith a pair of peripherally disposed vertical extruded members and apair of peripherally disposed horizontal extruded members secured tosaid vertical members, said sash members having a pair of offset spacedapart linear abutment surfaces adapted to engage the corresponding pairof spaced apart abutment surfaces of said frame members, at least oneswingable fulcrum arm pivoted to the sash and having a headed stud atone end adapted to slide in a confining manner in the slot formedbetween the walls of and` constituting the T-shaped channel of aco-acting vertical frame member.
